High EV-Yield Trainers

This page lists all the trainers who have Pokémon that yield the same kind of EV's. No more need to beat that same old Bidoof 100+ times in order to EV-train. Given the right tools you can speed up your EV-training by a tenfold.

Tools you might need are the power items and the VS Seeker. Also keep a booklet and a pen handy. This is EV-training after all and you don't want to mess up.
